Techniques of in vivo spectroscopy were employed to demonstrate the presence of rhythms of light absorption and scattering in the green thalloid alga Ulva lactuca L. maintained in artificial nutrient medium under constant photoperiod. The absorbance

On Friday evening, 8 November 1895, Wilhelm Conrad Rontgen, a 50‐year‐old professor of physics and recently elected rector of the Julius Maximilian University of Wurzburg, Germany, was unusually late for dinner. And when he did arrive at the fami

A Signal-to-Noise optimization model has now been extended to explain the range of species-specific polarization sensitivities of insects. The different polarization sensitivities are shown to represent optimizations for the detection of plane polari

Triethylsilyl hydrotrioxide (Et{sub 3}SiOOOH) is a new, short-lived oxidizing agent that can react at {minus}78{degree}C directly and rapidly with olefins to form 1,2-dioxetanes and oxidatively cleaved carbonyl products.

— Different genera of bioluminescent photosynthetic dinoflagellates exhibit different mechanisms for the inhibition of stimulable bioluminescence during daylight. These are (a) reduction in bioluminescence capacity, (b) increased refractoriness to

— The fractional photoinhibition of the mechanically stimulable bioluminescence in the vacuolar dinoflagellate Dissodinium lunula is proportional to the logarithm of the exposure. The action spectrum for this photoinhibition has been determined by

Mechanically stimulable bioluminescence and photoinhibition of sensitivity to mechanical stimulation in the marine dinoflagellate Gonyaulax polyedra can be mimicked by a number of cations, proportional to the logarithm of their external concentration

By methods previously described, the calcium-activated bioluminescent photoproteins were extracted with EDTA from the ctenophores Mnemiopsis sp. and Beroue ovata and then purified extensively. Two forms of the Mnemiopsis photoprotein, mnemiopsin-1 an

Species-specific rates of photosynthetic carbon uptake (P), chlorophyll a content and P versus irradiance (P-I), have been measured for cells of Pyrocystis noctiluca and P. fusiformis isolated from natural populations collected in the euphotic zone w
